AROUND THE WORLD DIRECTOR'S CORNER KEK’s science comic features the ILC Adapting to change by Philip Burrows by Rika Takahashi LC NewsLine will provide English versions of KEK's science comic "Kasoku Kids" from this issue. The comic exists since 2008, but this new series has a new protagonist: the ILC. The International Committee for Future Accelerators (ICFA) is a biannual gathering of the heads of major particle physics labs and institutes from around the world for the purpose of sharing news, liaising, and working together to promote global collaboration in our field. The Linear Collider Collaboration (LCC) has its mandate from ICFA, and the LC oversight Board (LCB) met in association with the recent ICFA meeting [see other article] to monitor progress on the three main LCC elements: the ILC, CLIC, and Detector & Physics groups.

Joachim Mnich, Research Director at DESY and the current chair of ICFA, Nigel Lockyer, Director of Fermilab, U.S., Fabiola Gianotti, DirectorGeneral of CERN, and Masanori Yamauchi, Director General of KEK sat at the conference, explaining the status of accelerator science in the world. Mnich introduced the mission of ICFA: it facilitates international collaboration in planning, construction and exploitation of accelerators for highenergy physics and related fields, and it has 40 years of history in international Masanori Yamauchi (left) and Joachim Mnich (right) at the ICFA press conference. Image: Nobuko Kobayashi collaboration. He said that ICFA’s major topic over the last years was the ILC. ICFA has proposed and promoted the ILC as a global project, and repeatedly confirmed its support for the ILC, which is in a mature state of technical development. “ICFA decided yesterday on its continuous study and support, and set up the sub group toward the realisation of the ILC” he concluded his talk with the decision made by ICFA’s meeting. Lockyer emphasised the international nature of particle physics, saying “particle physics has enjoyed international cooperation beyond any other field of science for many decades. We were able to exchange technical and scientific knowhow as well as culture, and people learning about science together.” He explained that the bottom quark was discovered at Fermilab, and the Belle experiment at KEK played a significant role to investigate the properties of the bottom quark. “The way particle physics goes is that you discover the particle, and you want to study it in detail. So, the ILC can study the Higgs boson in detail, in the same way KEK studied bottom quark in detail. A worldwide ambition is to study the Higgs in exquisite detail, which require a very special type of accelerator. The ILC is capable of doing that.” “You might think the Higgs boson is something far away from our everyday life, but actually it is not,” said Gianotti in her talk. “ This tiny particle is very, very special. Without the Higgs boson, our own existence is not possible,” she stressed the importance of further study of the Higgs boson. She said that many people often ask if the Higgs boson will change people’s lives, and her answer to that question is “it does already”. In order to find this particle, scientists have developed many cuttingedge technologies in many fields. She gave the example of the medical applications and also the world wide web, invented by the physicists to communicate with colleagues overseas, which has drastically changed the way we live. “The motivation for much of the research in particle physics is to go beyond Fabiola Gianotti, CERN, (left) answering a question from a the standard model,” Yamauchi said. “If we can go beyond the standard journalist (on the right: Nigel Lockyer, Fermilab) Image: Nobuko Kobayashi model, universal questions such as “what is dark matter?” or “why is there are no anti matter around us?” can be answered”. He said that world scientists are tackling this challenge by international collaboration and competition. “The ILC is one of the tools for nextgeneration research, and around the world scientists are hoping for its realisation. Now the Japanese government is carefully reviewing the project at the ILC Advisory Panel, and I hope positive conclusion is reached timely,” he said. One of the journalist asked Gianotti about the general critique for spending big budget on fundamental science research. “Fundamental research always benefits society,” Gianotti replied. She said that gaining fundamental knowledge itself is very important already. In addition to that, there are new technology developments and spinoffs in so many areas. She also made comparison on the CERN’s budget that it is about same scale of average mediumsize university in Europe, and “one cappuccino per European citizen per year.” She emphasised the important role of CERN in education that “it helps so many young people to grow. 3000 PhD students have studied at LHC experiments.” This conference was not like a usual press conference to announce a new discovery, but worked well to give the journalist the idea of true international collaboration.

This public relation tool has proven to work quite effectively to make new particle physics fans, especially very young children. KEK staff met some of reallife Kasoku Kids at the open house: They had memorised all the lines in the comics! From December 2015 to March 2016, KEK is publishing a new special series about the LC. LC NewsLine will provide an English version monthly from this issue. Enjoy! The English version of the first story was featured in Symmetry Magazine, but most of them are available in Japanese only. Find the English version of the ILC special here. For future physicists: the KEK’s Kasoku kids comic now features the ILC. ILC | JAPAN | KEK Copyright © 2016 LCC Printed from http://newsline.linearcollider.org DIRECTOR'S CORNER Adapting to change Philip Burrows | 10 March 2016 The International Committee for Future Accelerators (ICFA) is a biannual gathering of the heads of major particle physics labs and institutes from around the world for the purpose of sharing news, liaising, and working together to promote global collaboration in our field. The Linear Collider Collaboration (LCC) has its mandate from ICFA, and the LC oversight Board (LCB) met in association with the recent ICFA meeting [see other article] to monitor progress on the three main LCC elements: the ILC, CLIC, and Detector & Physics groups. One of the key issues discussed was the best way to proceed with organising global linearcollider affairs over the next few years. This will be a critical period during which several milestones will be reached: Group photo of ICFA meeting at JPARC, Tokai Village, Japan Image: KEK For the ILC we hope that the Japanese authorities will reach a conclusion on whether to proceed and implement the ILC in Japan. For CLIC there will be an intense preparation of a ‘Project Plan’ as input to the next update of the European Strategy for Particle Physics, so that CLIC can be considered (along with the Future Circular Collider (FCC)) as a possible postLHC energyfrontier facility. From the LHC we look forward to a stream of physics results from ‘Run 2’ as more data come in at the new maximum 13 TeV protonproton collision energy. As I said in my last Director’s Corner, we must be ready for what Nature has in store for us, even (especially!) if it is not something we had fully anticipated. A good example is provided by hints of a possible new particle state of mass 750 GeV, decaying into two photons, seen, with currently very modest statistical significance, by the LHC experiments ATLAS and CMS. More data will tell us if this is simply an upward statistical fluctuation of the background, or truly evidence for a new particle; but if the effect were real how would the linear collider community respond? Would we imagine a gammagamma collider for making a new 750GeV particle? In fact the idea of a gammagamma collider is not new and has been studied for as long as we have been planning linear colliders. Much work has been devoted by a band of dedicated experts to a conceptual design for a gammagamma collider. However, for the last decade or so most of us have imagined this option as a possible future extension to an electronpositron collider such as ILC or CLIC. Should the ATLAS and CMS hints motivate us to dust off the earlier design studies and look again at this concept? And, moreover, since only highenergy electrons are required for making high energy photons, should we think further about an electronelectron collider? This is another cherished old idea – has its time finally come? Of course we must be patient and allow the LHC data to speak, but it is fun to speculate, and it would be prudent to ‘expect the unexpected’. Returning to where I started – the ICFA meeting: an expert group was commissioned to come up with a proposal for guiding the LC community through these next few critical years. The group could hardly be more distinguished, comprising the Directors General of CERN and KEK, the Director of Fermilab, and the Research Director of DESY. We eagerly await their wisdom and good counsel – to be presented at the next ICFA meeting in Chicago in August – watch this space! 750GEV | CLIC | EUROPEAN STRATEGY FOR PARTICLE PHYSICS | FCC | HIGGS | ICFA | LCB | LHC Copyright © 2016 LCC Printed from http://newsline.linearcollider.org
